I know how to swap two numbers without using a third one.

a := a + b
b := a - b
a := a - b

I know better: a^=b^=a^=b;

I know how to reverse string in place.

void strrev(char *p)
{
  char *q = p;
  while(q && *q) ++q;
  for(--q; p < q; ++p, --q)
    *p = *p ^ *q,
    *q = *p ^ *q,
    *p = *p ^ *q;
}

b = b - a;
a = 2*a + b;

This isn't swapping, your b doesn't hold a, and your a holds (a + b) instead of b.

Good job, IHBT
a = 10 b = 7

b = 7 - 10
b = -3
a = 20 + -3
a = 17

The greatest secret in programming:
Bloat adds are a layer of memory that can be corrupted but will not affect the program, and the inefficient code - lower speed preserves the CPU from threats of electromigration/overheating damage.

lower speed preserves the CPU from threats of electromigration/overheating damage.

It's the opposite actually. Lower speed = more CPU cycles burned = more power consumption.

How do different clock speeds change the number of cycles for an opcode?
